36Kr learned that Renxin Technology, a domestic high-speed in-vehicle SerDes (Serializer/Deserializer) chip company, announced the completion of over 100 million RMB in Series A+ financing. As of now, the company's cumulative financing this year has reached nearly 300 million RMB. Old shareholder Desay SV continued to participate in this round of financing, and multiple investment institutions such as Jinpu Investment jointly participated. The financing funds will be mainly used for the large-scale mass production of in-vehicle SerDes chips, the improvement of the supply chain, and the R & D of new-generation high-speed products.

Renxin Technology was established in 2022, and its main business is the design and development of high-speed in-vehicle SerDes chips. Focusing on the R & D of in-vehicle SerDes technology, the company has achieved a full-range product layout from high-speed to low-speed and from Camera to Display.

SerDes chips are a key interconnection technology in the evolution of the automotive electronic and electrical architecture towards domain control and central integration. These chips are also known as the "neural network" of smart cars. They are mainly responsible for high-speed data transmission between sensors such as cameras and in-vehicle domain controllers and are widely used in functional scenarios such as 360-degree surround view, panoramic reversing images, smart cockpits, and ADAS. They have become a standard configuration for new energy vehicles and medium - and large - sized fuel vehicles.

Data from QYResearch shows that the global market size of in-vehicle SerDes chips reached 554 million US dollars in 2024 and is expected to exceed 1.949 billion US dollars by 2030. The global market size of in-vehicle SerDes chips is expected to grow rapidly, reaching 1.677 billion US dollars by 2030, and the Chinese market will have the fastest growth.

The SerDes chip market was previously monopolized by international giants such as ADI and TI. With the development of the new four modernizations trend in the automotive industry and the maturity of open protocols such as HSMT and MIPI A - PHY, domestic SerDes suppliers have gradually emerged in recent years, showing a trend of domestic substitution.

36Kr learned that after years of development, Renxin Technology has formed a complete product layout: its 16Gbps Camera SerDes chip was mass - produced and delivered in 2024, and the newly developed 32Gbps Display SerDes chip supports the high - bandwidth requirements under the integrated cockpit and driving architecture and can drive up to 8 displays.

In terms of product technology, Renxin Technology's core advantages are reflected in its system architecture design and reliability engineering. The aggregation and forwarding architecture it uses can effectively reduce the number of SerDes used, achieving system - level cost reduction for vehicle manufacturers. More importantly, since the initial stage of product design, the company has strictly followed the strict standards of automotive - grade chips. After a two - and - a - half - year R & D and verification cycle, it has successfully passed the product function certification of an international authoritative organization. This is also the first in - vehicle high - speed SerDes product functional safety certificate in China. In addition, Renxin's products perform outstandingly in reliability functions such as breakpoint detection and hot - plugging, ensuring long - term stable operation in complex in - vehicle environments.

In terms of the sales market, since the mass production of Renxin Technology's R - LinC chip, it has been mass - produced in multiple automobile manufacturers. In the ecosystem, Renxin has received high recognition and support from leading domestic and foreign SOC manufacturers, completed the adaptation work for multiple mainstream platforms, and entered their official certification and recommended component lists.

In terms of team strength, the core team members of Renxin Technology all come from globally leading chip design companies and leading automobile manufacturers and have accumulated rich experience in high - speed SerDes development, automotive chip engineering, and commercialization. The company's headquarters is located in Hangzhou, and it has established operation and R & D centers in Shanghai and Chengdu. It currently has about 130 employees, mainly R & D and engineering technicians.

Investors' Views:

Desay SV: Renxin Technology has outstanding performance in core indicators such as performance, stability, and reliability due to its excellent product quality. Its systematic cost - reduction ability also effectively helps customers optimize costs and improve efficiency, winning high recognition from the industry and customers, and its market reputation continues to rise. These achievements fully confirm Renxin Technology's profound technical accumulation and solid strength in engineering implementation and mass production. The two parties will further deepen cooperation to continuously provide more competitive system and product solutions for the smart car industry.

Jinpu Investment: As a new shareholder in this round of financing, Jinpu Investment has long - term attention and in - depth investigation of Renxin Technology and fully recognizes the company's forward - looking vision and execution ability in strategic planning, technology R & D, and business management. At present, the company's in - vehicle products have been mass - produced and delivered. Not only do the product performance and reliability reach the advanced level in the industry, but the products also directly address the pain points in meeting customer needs. We believe that with solid technical accumulation, excellent financing ability, and a clear development strategy, Renxin Technology will continue to release growth potential in the high - speed SerDes field and show higher industrial value.
